2017 Mercury 115 Pro XS

[samwise2u]

Taking the boat out tomorrow on its maiden voyage. Just to summarize what has been read in the manual and read in this forum about the break in. I am apprehensive about this whole thing.

Book says, for the first 2 hours, vary the engine up to 4500 RPM (3/4 throttle) and at full throttle for 1 minute every 10 minutes.

Forum says the same thing above but adds keep motor trimmed down, warm up the engine for 5 minutes or more before taking off and have at least one cool down during the first two hours.

Water temp in north Louisiana is 55+.

Did I miss anything? Any suggestions?

Do what the sticky states.
If you trim the motor all the way up the break-in counter may NOT count down.

You don't trim it over vertical for the first two hours since your trying to load the motor to wear in the rings.

[samwise2u]

First 2 hours are completed. Everything went well. Now for the next eight.

Would it void the warranty if I changed oil myself after the 10 break in?

[Savage]

No.

[EuropeanAM]

Certainly won't. Just make sure you use the RIGHT oil, RIGHT filter, and perform the task correctly (any errors in those areas could affect a future claim).

Please see the Forum Announcements, and be sure to provide the REQUIRED info when posting. Moving your thread to the 4-stroke forum for ya.

Someone correct me if I'm wrong, but I thought (if the oil looked fine and the level wasn't going high or low) the first oil change wasn't until 20 hours?

[EuropeanAM]

20 hours is the suggested interval for the first oil change (and gear lube).
